Screw Cap Microtube

SCILAB Screw Cap Microtubes are premium, precision-engineered 0.5 mL 1.5 mL and 2.0 mL tubes designed for the secure, long-term storage of sensitive molecular biology samples. Featuring a fine external thread and an O-ring sealing design, they deliver exceptional performance for demanding applications like PCR, qPCR, and enzymatic assays, while their compact, stackable design is fully compatible with automated liquid handling workflows.

Solving Key Lab Challenges:
• Guarantees Superior Seal Integrity and Prevents Evaporation: The precision-molded screw cap, combined with a silicon O-ring, creates a secure, leak-proof, and vapor-tight seal. This effectively prevents sample evaporation, freeze-drying, and cross-contamination during high-speed centrifugation, thermal cycling, and long-term cryogenic storage.
• Ensures Sample Purity and Prevents Adsorption: Manufactured from ultra-pure, medical-grade polypropylene with a smooth, low-binding inner surface, these tubes minimize the adsorption of precious biomolecules like proteins, DNA, and RNA. This ensures maximum sample recovery and integrity for downstream analysis.
• Optimizes for Thermal and Chemical Resistance: The tubes withstand repeated heating in thermal cyclers (>100°C), without cracking or deforming. They are also highly resistant to a broad range of chemicals, including alcohols, acids, and bases.
• Enhances Workflow Efficiency and Organization: The uniform external dimensions and flat cap design allow for secure, space-saving vertical stacking in freezer boxes and on lab benches. Color-coded caps facilitate rapid visual identification of different sample types or projects, streamlining sample management.
